Abstract
The present invention provides hierarchical assemblies of a block copolymer, a bifunctional linking compound and a nanoparticle. The block copolymers form one micro-domain and the nanoparticles another micro-domain.
Claims20
A composition comprising:
- a plurality of nanoparticles each having a ligand linked to a surface of each of the nanoparticles;
- a plurality of block copolymers, each block copolymer comprising a first block and a second block;
- and
- a plurality of bifunctional linking compounds, each bifunctional linking compound non-covalently links to one block of one of the block copolymers and to the ligand on the surface of each of the nanoparticles, wherein the plurality of nanoparticles are arranged in an array to form a first micro-domain, and the block copolymers form a second micro-domain, and the composition is a solid below the glass transition temperature of the plurality of block copolymers.
